If I build a power plant and the scientist on the project tile is mine, I have to remove him. So can I dicide to keep him in my hand and earning 1 expertise or send him to a summit topic like the same case if an other player remove him as a part of his action?
Thanks for answer
When you build the power plant, you have to use your Free Scientist Move action to move your scientist away first, then you can build. This is different from what happens when you kick out someone else's scientist. You can move your scientist anywhere allowed by the Free Scientist Move action (which obviously doesn't earn you any expertise at that time).
